About this 3D model

I ordered some new PLA from OSPWRD.com, and they came on these bigger spools, so I made some fittings to mount them with bearings on a piece of threaded rod. I guess I have humidity problems, cause all of the laser-cut spools and coasters I have are all warped to hell, so they don't work all that well. At least I could scavenge the old ones for the bearings. :D I also made a stand, but it's kinda junk, so I'll upload that after I rebuild it.
